How to Jailbreak iPhone 4S iOS 6.1.1 with Evasi0n

Step 1

Make sure that your iPhone 4S is running iOS 6.1.1 A clean/fresh restore is always recommended if you want to jailbreak your device. Here’s how to update to iOS 6.1.1. Direct update is not recommended for UltraSn0w unlockers.

Step 2

Download Evasi0n and extract it;
Run the evasi0n and plug in your iPhone 4S;
Evasi0n should detect your iPhone 4S and the jailbreak button will be activated;
Click the Jailbreak button;
Evasi0n will perform several jailbreaking steps including preparing jailbreak data, injecting jailbreak data, and will reboot the device;
After reboot it will upload stage 2, uploading Cydia, and uploading the Cydia packages list. The jailbreak process may take a few minutes, so be patient;
Evasi0n will ask you to Slide to unlock your device. Once your device is unlocked, you should find a new icon called “jailbreak” on your iPhone’s home screen.

Step 3

Tap this Jailbreak app icon (just once), and the screen will go black and then return to the Home screen;
Evasi0n will again process and show more message like injecting jb data messages, and Root Filesystem successfully remounted.
A “Done!” message will appear on evasi0n tool. Your device will now reboot;
First time boot after jailbreak will take some time, so be patient. Your device may restart several times.

An evasi0n logo will appear on your screen and several messages will appear on your iPhone’s screen. Once the process is completed, your iPhone will boot to lock screen. Unlock your iPhone 4S and find the sweet Cydia icon on your springboard.

Troubleshooting

If the process gets stuck somewhere, it’s safe to restart the program, reboot the device (if necessary by holding down Hold and Home until it shuts down), and rerun the process.
If the device is stuck displaying “patching kernel”, you can press Power+Home for a long time to force a reboot.

I updated y iPhone 4s to the new 6.1.1. to overcome 3G connectivity issues and after the Apple update to 6.1.1 and Jailbreaked with evasi0n 1.3, I still don’t have 3G connection. At the moment, my iPhone is useless when out of the house as I cannot send, receive or use the internet when there is no 3G!
What happens now? evasi0n states that as my iPhone 4s is already Jailbroken, Jailbreaking again is not recommended.
